After some consideration, the imperial court believed that the threat of Zhao to Jiangnan was quite great, and let more people gather in Jianghuai was a good guarantee for the safety of the capital of the Great Jin Dynasty, and this kind of half-army and half-civilian Tuntian people would not add a little burden to the treasury, but could also hand over a part of the income from Tuntian, so they agreed to Hua'an's request, let the 20,000 recruits of the Northern Expeditionary Army go to Tuntian, Jiangbei, and allocated a large piece of barren land near Jiangbei to the Northern Expeditionary Army.

Thousands of hectares of wasteland need to be sorted out and planned to become fertile land, for this reason, Hua'an deliberately took several officials who are proficient in water conservancy construction to investigate, after more than half of the field exploration, the preliminary determination of the transformation plan, and then revised several times, a month later, officially began to sort out the wasteland.

20,000 horses crossed the river into the north of the river, and built a large camp on a high ground near the river, after the large camp was built, 20,000 horses could enter the fields to work, if the 20,000 horses worked together, it would naturally speed up the progress of the project, but in this way, the level of combat skills would definitely decline, so that the 20,000 horses would become out-and-out peasants.

In order to keep the 20,000 recruits in combat and have the ability to fight at any time, Hua'an took turns to send officers to the large camp in Jiangbei to guide the training, and the 20,000 horses were divided into two groups to take turns to train and work in the fields, changing every three days, so that they could not only maintain their combat effectiveness, but also would not affect the tasks in Tuntian.

It takes a certain amount of time from tidying up the wasteland to the maturity of the crops planted, and during this period of time, the 20,000 horses in Jiangbei have no harvest, but since Hua'an insists on keeping them, he naturally regards them as his subordinates, and for this reason, the problem of eating and drinking is completely the responsibility of the baggage battalion of the Northern Expeditionary Army, and the granary in Jiangnan still has nearly one million denier of military rations, which is enough to support them.

In just two months, the division of the fields and the construction of ditches have been completed, which greatly exceeded Hua'an's expectations, which is much smoother than when Jiangnan sorted out the wasteland.

Of course, the reason why it is so smooth is that many of the wastelands here were originally fertile fields, and the ditches were also ready-made, but due to the southward migration of the population, the land was temporarily deserted, and as long as it was slightly organized, it could become fertile land that could be cultivated.

After the fields are finished, it has entered autumn, and the tuntian land in the south of the Yangtze River has entered the harvest season, and the tuntian land in the north of the river has also begun to cultivate the next season's crops.

Farming, harvesting, plowing, harvesting, and so on, two years later, in 344 A.D., the granary of the Northern Expeditionary Army in the south of the Yangtze River has hoarded two million denier of military rations, the cattle and sheep in the pasture are grazing on the grass one by one, and there are tens of thousands of foals, galloping up on the pasture is extremely spectacular, of which there are more than 6,000 foals of the third year, and there are more foals of one or two years.

In order to make these foals become brave war horses on the battlefield in the future, Hua'an let the soldiers start training their pace from the foal at the age of one year, and began to place the saddle and stirrup at the age of two, and the soldiers rode appropriately to train them to withstand the endurance of the human body, and the three-year-old war horse began to carry out standard riding training, the horse of this age can already be used as a war horse, but the strength is definitely not good, and the most suitable age for the war horse is five to fifteen years old.

In addition to training war horses, the riding training of soldiers of the Northern Expeditionary Army has also been popularized to the whole army, Hua'an's goal is to make every soldier under his command proficient in horsemanship, can be used as cavalry, dismounted can be used as cavalry, dismounted can be used for foot combat, unloading armor can be farmed, this is a qualified Northern Expeditionary Army soldier.

Tens of thousands of foals will soon grow up, and the day when everyone with a horse for the 30,000 soldiers of the Northern Expeditionary Army is not far off, Hua'an even plans to equip each soldier with two war horses, which can save horsepower and improve combat ability, of course, these are all things in the future, and they can't be done for the time being.

The most precious livestock in the pasture is naturally the raised elk, in addition to the dozen or so that Hua'an captured alive at the beginning, and later the soldiers of the Northern Expeditionary Army captured a batch alive from the woods in the south of the Yangtze River. Today, there are thousands of these elks that breed every year.

The whole body of the elk is a treasure, the antler velvet is a precious Chinese medicinal material, the venison is rich in nutrition, won the favor of the royal family and nobles, the deer skin is a high-quality leather raw material, can be made into clothes or leather armor, deer blood and deer whip is the favorite of men.

There are so many elk in the pasture of the Northern Expeditionary Army, which will naturally attract the attention of the royal nobles and children of the scholar clan in the capital, and they will go to the ranch of the Northern Expeditionary Army from time to time to ask for or buy elk in the name of visiting.

In this regard, Hua'an will sell some according to the actual situation, and a small number of people who open their mouths to ask for are the children of the royal family with very high status or great strength, for them, Hua'an is not stingy, directly gifted, and even without them opening their mouths, as long as they see that they have the intention of asking for it, they will give it directly to them, not because they are afraid of them, but to enhance each other's feelings, consolidate their position in the Great Jin, and reduce the difficulties and false accusations of the ministers of the DPRK and China in the future.

Of course, the best elk must be presented to the emperor of the dynasty, and every month, Hua'an will send soldiers to present a pair of elk to the palace to the emperor Sima Yue.

However, the emperor Sima Yue's health is really too bad, even if he eats the venison every day, his body is still getting worse, he has to be supported by eunuchs when he goes to court, and from time to time he will be dizzy in the court, which makes the ministers of the Manchu Dynasty worried, and at the same time, it is also bitter for the ladies of the **, the eldest queen Chu Garlic, is now only twenty years old, the emperor is weak, and they have to stay alone in the empty room when they are in their prime age, and they are in a daze when they can't sleep at night.

The emperor is not in good health, but there is an urgent report from the frontier, the Nanyue people in the south of Jiaozhou, at the instigation of the monarch of Shu to launch a rebellion, now the rebels have invaded the territory of Guangzhou to the north, Guangzhou Assassin Shi Deng Yue led troops to resist, but the shape is still very critical, the most terrible thing is that the 30,000 horses of Shu have been stationed in Xinggu County in the west of Guangzhou, and it is possible to reinforce the rebels in the east at any time.

Receiving the news of the rebellion of the Nanyue people in Jiaozhou, Emperor Sima Yue was shocked, and fainted in the court at that time, and the ministers of the court were also panicked when they saw the Son of Heaven fainting.

After several hours of continuous deliberation, several important ministers of the court decided to send a main army into Guangzhou to quell the rebellion together with the defenders of Guangzhou.
